Application filed February 17, 1886. ScrialNo.19-2,307. (No model.)

To all whom it may concern: ml or scroll. The bodies of the dogs are ofBe it known that I, ARTHUR J. SANDS, a the same thickness as the sidesof the barrel citizen of the United States, and a resident of andcorrespond in shape to them, and a disk, Schenectady, in the'eounty ofSchenectad y and H, fits and revolves with its central aperture, 5: 5State of New York, have invented certain new I, upon the barrel and uponthe rear ends of and usefulImprovementsin Chucks forBroomthe dogs,having a spiral flange or scroll, J, \Vinding Machines; and I- do herebydeclare upon its forward face, which corresponds to that the followingis afull, clear, and exact the scroll, of which the lugs upon the dogsdescription of the invention, which will enform portions, and having thesaidlugs fitting 6 1o able others skilled in the art to which it apinthe spiral space between the windings of the pertains to make and usethe same, reference spiral flange.

with wire and finished; and it consists in the A casting, It, is securedto the supportingimproved construction and combination of frame of thechuck, and hasabearing, S,which parts of such a chuck, as hereinaftermore fully fits upon the collar upon the barrel, and one described andclaimed. a side of this casting is formed with a recess, T, 5 In theaccompanying drawings, the letter A opening into the side of thebearing, and havindicates the barrel, which may have any suiting ablock, U, sliding within it, the inner end able means for revolving it,and which may be of which block is cylindrically concaved, so asjournaled in any suitable manner, and this to bear against and fit uponthe collar of the barrel is provided with a number of equidis barrel. Acam -levcr, V. is pivoted within 4o tant longitudinal slots, B, openingnear the the recess, and bears with its cam-head against outer end ofthe barrel, and extending to withthe outer side of the block, and has acord or in a short distance of a collar, 0, upon the rod, X, secured toits outer arm, for the purbarrel, the said slots opening radiallythrough pose of drawing the said arm down so as to the sides of thetubular barrel. Dogs D fit bring the head to bear against the block, and5 5 with their inner long bodies, E, in the slots thus force the blockagainst the collar, holdand slide radially within them, and these dogsing the same rigidly, and preventing the spinare provided at their outersides with outdle from revolving. wardly-projecting arms F, having aseries of The inner face of the front plate or cap is equidistant lugs,G, upon their rear faces, the formed with radiating groovesY,withinwhich ICO 50 said lugs being of the same height and thickthe forwardsides of the outwardly-projecting ness and forming portions of asquare-cutspiarms of the dogs may slide and be guided, and

the outer face of the plate is provided with outwardly-projecting pinsZ, upon which the bands or straps can be hung when they are used inmaking the broom.

It will thus be seen that the handle of a broom maybe inserted into thetubular barrel and be held firmly within it by the dogs,which may beforced simultaneously against the handle by the scroll and hand-wheel,and the barrel will be prevented from revolving when the hand-wheel andscroll are revolved, tightening the dogs by depressing the outer handleof the cam-lever, which will force the brakeblock against the collarofthe barrel, preventing it from moving.

. This chuck is principally intended for the purpose of holding thehandles of brooms while they are being wrapped with wire and finished,but it follows that the chuck may be used for holding any other objects,and the spiral scroll will exert considerable force upon the dogs,holding the object firmly.

The chuck is so constructed that it may be taken apart in pieces, whichall may be replaced by corresponding parts, if any parts should becomedamaged, and the scroll'disk and dogs, which are especially subjected towear, may be removed from the barrel and from the hand-wheel, retainingall other parts, which are not so exposed to wear, the scrolldisk beingonly connected to the hand-wheel by the rearwardly-projecting pins uponits rear face, which pins fit into perforations or recesses in theforward face of the hand-wheel.

Having thus described my invention, Iclaim and desire to secure byLetters Patent of the United States- 1. In a chuck, the combination ofabarrel having radiating slots, dogs sliding radially in the said slotsand having their rear faces provided with lugs forming parts of a spiralscroll, and a hand-wheel turning upon the barrel and having a spiralscroll orflange upon its forward face engaging the lugs upon the rearfaces of the dogs, as and for the purpose shown and set forth.

2. In a chuck, the combination of a barrel having radiating slots, dogssliding radially in the said slots and having their rear faces providedwith lugs forming parts of a spiral scroll, a disk having a spiralscroll or flange upon its forward face engaging the lugs of the dogs andhaving pins upon its rear face, and

a hand-wheel turning upon the barrel to the rear of the scrolldisk andhaving pcrforations or recesses in its forward face for the reception ofthe pins of the scrolldisk, as and for the purpose shown and set forth.

3. In a chuck, the combination of a barrel having radiating slots in itsforward end and having a shoulder or collar, dogs sliding radially inthe said slots and having radiating arms upon their outer sides providedwith lugs upon their rear faces forming parts of a spiral scroll, a diskturning upon the barrel and having a spiral scroll or flange upon itsforward face and having rearwardly-projecting pins upon its rear face, ahand-wheel turning upon the barrel and having perforations in itsforward face for the pins of the scroll-disk and having aforwardly-projecting annular flange projecting beyond the forward sidesof the arms of the dogs, and a cap or disk fitting with its edge withinthe outer end of the easing formed by the flange,and having radiatinggrooves in its rear face for the arms of the dogs being secured to thebarrel, as and for the purpose shown and set forth.

at. In a chuck, the combination of a barrel having a collar, a rigidcasting formed with a bearing for the collar and with a recess, a blocksliding in the inner portion of the said recess and having its inner endconcaved to [it against the collar, and a camlever pivoted in the outerendof the recess of the casting and having its inner cam-shaped endbearing against the outer end of the block, and having its outer armprovided with means for tilting it, as and for the purpose shown and setforth.

5. The combination of a chuck-barrel having radially-sliding dogs andmeans for operating the said dogs, a bearing for a shoulder or collar ofthe said barrel having a recess opening into one side of the same, ablock fitting against the collar and sliding in the recess, and acam-lever bearing with its eccentric head against the block, as and forthe purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

ARTHUR J. SANDS.
